Summary of the invention
But the in the situation that of the processed objects of Plastic such as flexible plastic, the flinders of the small grain size being broken is stranded between disintegrating machine main body and rotor tip (" flinders " comprises " broken powder " in the specification and claims), this flinders is due to fricative heat in service etc. and melting, if make machine out of service under this state, the flinders of melting is cooling, solidifies and adheres to.And flinders solidifies while being attached between rotor tip and disintegrating machine body like this, sometimes can be in the upper faults such as difficulty in starting that occur while once starting.
Again, the in the situation that of this single-shaft crusher, in order to make between the engaging-in rotation blade of processed object and counteredge in crushing chamber, propeller is entered in crushing chamber, therefore the small grain size flinders in crushing chamber likely drains to propeller resettlement section one side of disintegrating machine main body in the time that propeller retreats, likely drain to outside machine, likely cause surrounding environment deteriorated.
And because formation makes the guider of above-mentioned propeller advance and retreat and the pressure cylinder (cylinder that propeller is advanced and retreat, シ リ Application ダ) (power part) structure of contacting with flinders, therefore sometimes this flinders can make the each portion of pressure cylinder wear away, impeller driven portion premature wear, sometimes have to implement ahead of time to maintain, carry out parts replacement.
Further, even as patent documentation 1 from rotor to radial direction blowing out pressurised air, can not prevent that the small grain size flinders after fragmentation is stranded between rotary body and fixed body.And multiple holes that blow out must be set in rotor radius direction, and the compressed-air actuated passage of guiding is set simultaneously in rotor, it is complicated that the structure of rotor becomes, and needs more expense and time.
Therefore, the object of the invention is to, provide and can stably small grain size flinders be discharged to passing away, can carry out the single-shaft crusher of stable small grain size fragmentation.
To achieve these goals, single-shaft crusher of the present invention possesses the rotor of the rotation that arranges multiple rotation blades on direction of principal axis, arrange at disintegrating machine main body side, can and the rotation blade of this rotor between processed object is carried out to broken counteredge, the mesh screen of below given size, processed object broken between this counteredge and described rotation blade being discharged to passing away, store the crushing chamber of the processed object that offers described rotation blade, and advance and retreat from the propeller resettlement section of described disintegrating machine main body, the processed object of this crushing chamber is pushed to the propeller of described rotor, described disintegrating machine main body has the discharge means that the flinders of the small grain size in described crushing chamber is discharged, these discharge means possess at the passing away between the both ends of described rotor and described disintegrating machine main body with the space that the flinders out of the gap between this rotor and disintegrating machine main body can be discharged.By means of this, even the flinders of small grain size spills from the both ends of the rotor as rotary body and as the gap between the disintegrating machine main body of fixed body, also can discharge from passing away without being detained, even if the flinders being therefore broken is the processed objects such as such as flexible plastic, also can between rotor and disintegrating machine main body, not discharge to passing away to melting, can carry out steadily in the long term the fragmentation of small grain size.
Again, the present invention also can possess the rotor of the rotation that arranges multiple rotation blades on direction of principal axis, arrange at disintegrating machine main body side, can and the rotation blade of this rotor between processed object is carried out to broken counteredge, the mesh screen of below given size, processed object broken between this counteredge and described rotation blade being discharged to passing away, store the crushing chamber of the processed object that offers described rotation blade, and advance and retreat from the propeller resettlement section of described disintegrating machine main body, the processed object of this crushing chamber is pushed to the propeller of described rotor, described disintegrating machine main body has the discharge means that the flinders of the small grain size in described crushing chamber is discharged, and these discharge means possess the drain passageway that the flinders from drain to described propeller resettlement section one side to the described angle of rake upper surface of described crushing chamber advance and retreat is discharged to this propeller below and utilize this angle of rake advance and retreat action to discharge the scraper plate of described flinders.By means of this, can utilize the reciprocating motion scraper plate of propeller advance and retreat is discharged the flinders of the small grain size that drains to propeller resettlement section one side in crushing chamber to drain passageway, therefore can suppress small grain size flinders and leak to outside from disintegrating machine main body.
And described propeller has along the suspension type linear steering device of the rail moving of configuration downwards of the lateral surface in described disintegrating machine main body, has the actuator that linear steering device is moved along this track at the lateral surface of described disintegrating machine main body.If done like this, because utilization makes to push to rotate processed object the propeller of blade to along the linear steering device guiding of the sus-pension of rail moving, the coefficient of friction that can reduce to make the part that propeller moves, successfully moves it, can push rotate processed object to blade.And support angle of rake linear steering device and track and actuator owing to arranging at the lateral surface of disintegrating machine main body, can prevent that the flinders of small grain size from adhering to, be piled up in the situation generation that causes the each several part such as actuator and linear steering device generation abrasion on actuator, linear steering device and the track as operating member.
Again can described scraper plate there is engineering plastic flitch and by this project plastic plate to the elastomer of scraping bevel and energizing.This engineering plastic flitch preferably adopts high-molecular polythene, because it has abrasion performance and self-lubricating property.Elastomer preferably adopts the endless elastomeric (such as rubber tube etc.) that the central portion of engineering plastic flitch is energized.If done like this, fatigue (へ り) that can long term inhibition scraper plate and abrasion, can keep its scraping function steadily in the long term.
